Toyota - Tacoma :: 1999 - Surges Forward At Random Intervals While Idling

I have a 1999 toyota tacoma 70,000/mi. While idling, at random intervals, truck surges forward. Have to stay on the brake. Cannot drive in winter. Took to Toyota dealer and other mechanics... described problem and that A/C seems to be on all the time. No one has been able to fix. My brother disconnected the A/C and surging has stopped, but I need a better fix that will allow my using AC.

Ford A/C :: Cooling System Won't Work When Idling - Surges - Thermostat Open After Engine Rave?

My 5.8L XL Windsor van is overheating when idling or in traffic but cooling just fine when moving on highways.

The 5 blade-fan comes on as soon as I turn the engine on and the radiator appears to be working just fine, cooling fluid moving and no leaks.

I am a landscaper in NYC and often haul heavy loads through slow moving traffic in the city and would love to drive relaxed and not with my eyes fixed on the temperature gauge awaiting impending disaster.

What is the best course of action?

a) change the clutch and see how it goes...

b) change the clutch, the fan and the water pump

c) install an electric fan

d) drive the van into the east river

Another issue, which has me and my friends puzzled, is that I changed the termostat a while back in an attempt to locate the problem; I replaced the old 195 degrees with a 180. Since the change 8 times out of 10 when I start the van as it is warming up I have to rave the engine for the termostat to open otherwise it does not and I end up with overheating bang. Once it is open no problem beside the overheating while idling.

And one final issue after driving for a while the motor surges when idling at a stop light or in heavy traffic. I have been thinking a bad air sensor but my mechanic or I have not been able to fix this issue for years.

Passat (B5) :: 2003 - When Driving At Constant Speed The Engine Surges About Once Every Second Or Two

We have a 2003 Passat GLX, 43000 miles, V6, AWD. I've noticed recently that when driving at constant speed the engine will surge about once every second or two. It's very regular, and on a smooth road I can also notice a bump in the drive train, very similar to road bumps.

I've taken it to a dealer, since I believe it is a transmission issue, and therefor covered under warranty. There are no computer codes stored for faults in the transmission, they've said. However, they started by pursuing the fuel injection system (though no code was stored), and then wanted to fix a faulty coolant sensor (since found not to be faulty).

Camry :: 2006 Toyota Surges At Any Speed / Loss Of Power - Code P0420

Symptoms:
-Car "Surges" at any speed. Loss of power is significant.
-Check engine light is on , DTC code = P0420

Tried:
-Fuel injector cleaner
-Spark plugs replaced around 40k miles ago
-Checked for leaking valve cover gasket (oil in plug wells) None

Can a clogged fuel filter cause this? At idle the car is fine, the symptoms seem to only occur when car is under load (In drive). My son drove this car an it always seemed empty meaning he never put much gas in it.

Passat (B6) :: 3.6 Stall After Idling

My 2006 Passat 3.6 developed this problem very recently and wanted some opinion as to what could be wrong before taking it to the dealer as it's now out of warranty with 115,000k.

Basically, once the oil reaches 90C, the car will stall after idling for a few minutes. The revs will hover at the 600 mark, and it will just stall. I can turn it back on right after without any issues and can also prevent this from happening by keeping the revs up myself while stopped...

The idle is also a bit rough: the revs are stable on the tach, but I can feel some vibration in the cabin which wasn't there before...

Saab - 9-3x :: 2006 - CEL Came On / Idling And Stalling?

I have a 2006 Saab 9-3 Aero that I bought back in August. Two weeks ago, I brought car into the dealership for a 90k road service. It had some idling issues (sometimes, upon starting it up (cold or not), the car would idle and sputter, but never actually die. During the tune up, they said there was a frayed cable, which they replaced.

Fast forward 1.5 weeks later. The check engine light has come on. And the car is now sometimes idling funny just as it was before, only now it actually sputters and actually dies sometimes upon start up. After it initially dies, if I start it up again, it runs fine up on the second start.

Took into the dealership this morning and after 2 hours of diagnosis, they say the check engine read-out is indicating the fuel pump pressure sensor is going out, and that's what's causing it to idle and stall. Is this diagnosis legit?

Camry :: 2006 - Idling Very Rough

My Dad Purchased an 06 Camry, 2AZ-Fe engine w/140,000 miles on it from a family member. He was told that the engine had some issues but wasn't specific about the problem. He recently passed and left the car to me. I used to be a mechanic but i have little knowledge on Toyota. The car cranks/starts easy, but idles very rough. I scanned it and the codes I retrieved were p0300,0301,0302,0304. I haven't done a compression test or a leak down yet, but plan to tomorrow. I also will check resistance on the coils and check the condition of the plugs. I looked through some old posts on here, and seen this engine has head bolt issues. pcv issues. and oil consumption issues. Should i pursue trying to fix this or leave this project alone.

Passat (B6) :: 3.6L Engine Is Idling A Bit Rough

Just noticed the other day the Passat was idling significantly rougher than usual, most of the time it's smooth as butter but not so much lately. It's not rough like a bad misfire, just not very smooth anymore. This could be indicative of the dreaded oil-pump bolt failure rearing it's ugly head (finally)?

Passat (B6) :: Idling On 2500 RPM On Neutral

I was going downhill. And I accidentally popped the car in neutral. Its a 2.0t fsi automatic transmission. And after putting it back in drive mode. The car went to 2nd gear and jerked the tires. I had to put it back in neutral because it was revving high rpm and it wouldn't switch. After I came to a full stop. The car was idling on 2500 rpm on neutral. I got an intake installed and replaced the pcv valve with one I got from ecs tuning last week. I am assuming I have a transmission problem.

Passat (B5) :: Car Turned Off By Itself While Idling For Less Than A Minute

So my car was fine when I drove to the store, with no AC on. After that, I wanted to drive to a hotel, which is 1/2 of a mile away. Before I drove there and after I started my car, I blasted my AC (turning up to #3). On my way there the car was fine. When I drove into the parking lot and braked, the car suddenly turned off by itself showing the battery light. After the car turned off by itself, the fan (not AC..

AC doesn't run when engine is turned off) was still running. I freaked out, immediately turned AC/Fan off and restarted it. It was successful after the first try. So my question is...what caused the car to turn off by itself? Is it because of my AC? I know FOR SURE...it's not because of

1. timing belt because i recently changed it.
2. battery but i installed a brand new last summer.

Accent MC (2006-11) :: Shaking And Idling Really Rough

I have a 2006 Hyundai Accent that won't start. My wife was driving home the other day, and while she was sitting at the light she said she noticed a sudden change in the idle. She said the car starting shaking a little and idling really rough. When she tried to accelerate after the light changed, she said the car sputtered and would barely go.

She was only a couple of blocks from the house so she continued home. The car made it the rest of the way home, but she said it never went over about 5 mph even though she was pressing the accelerator as she would if she were going about 30...the car just never responded. When she pulled into the garage the car died as she was turning. Now it will crank but it won't start at all.

I tested the crankshaft position sensor with my multimeter and it was bad. I bought a new one and put it on, and I tested it immediately. The new one works, so I plugged everything back in and tried to start the car...nothing, just cranks and won't start. It's getting fuel and fire as well (tested both), but it's not hitting on any of the cylinders.

Passat (B5) :: Clicking Noise After 2 To 3 Minutes While Idling

When the engine is cold and I start it, everything is just perfect. After 2 to 3 minutes while idling I start hearing a clicking noise, which is not loud, but I don't like it. I'm sure that there was no noise before. I cannot locate the exact location but it is surely somewhere near the air filter. When I'm close to the front right wheel the noise is most clear and when I lean back behind the wheel.
